According to ICANN's privacy service definition:
Privacy services allow a domain name holder (registrant) to be listed as the registrant of record but with alternate, valid contact information (such as a mail-forwarding service address) published in place of the registrant's home address.
In simple words, with Privacy Protection you can hide your private information from your domain's WHOIS result page.
We have build a custom tailored ticketing system to accomodate communication between interested party and domain holder/registrant. Only non-spam emails/messages will be delivered to domain holder/registrant.
